The minimum aluminum conductor of size ________ is used for a subcircuit in domestic wiring.
The minimum aluminum conductor of size ________ is used for a subcircuit in domestic wiring.
Right Answer is:
1/1.4 mm
SOLUTION
It is essential to determine the conductor size. It should also be known whether a copper or aluminum conductor is to be used. The sizes and prices of copper and aluminum conductors largely differ. The points to be considered while calculating the size of the conductor are current carrying capacity, voltage drop in conductor and minimum permissible size of the conductor.
The current carrying capacity of a circuit depends on the total connected load. Thus, knowing the total load connected to the circuit, the conductor should be selected as per IS codes.
The minimum size of the conductor in the sub-circuit should not be less than 1/8 in the case of copper wires and 1/1.4 mm (1.5 mm2) in the case of aluminum wires.
